Creating a print event handler in a class, and calling it from my print dialog, I need human help on this

jkirkerx

This is my first time trying to to print directly to a printer using the PrintDialog and PrintDocument. I thought it would be like creating a PDF, where I just compose and create a file and print, but it looks like I'm forced to use an event handler to compose my print document using Drawing. I was on the internet, and the examples where very simple and basic, but my document is going to be huge, and used many times in my c# winforms .Net Core 7 app. So I used ChatGPT to help me design a class, that I can call as my event handler, but I'm missing something in my class, or got it wrong on how all of this works. On my Print Dialog Form, when I hit the print button, my code example ... The printDefault.Question is what I'm trying to call, where Question is where I'm stumped ..

if (result == DialogResult.OK)
{
// Record the printer name used when the print job was accepted
this.PrintObject.PrintSettings.DefaultPrinter = printDialog.PrinterSettings.PrinterName;

if (this.PrintObject.PrintSettings.DefaultDocument != null)
{
    var printDefault = new PrintDefault
    {
        Bol = this.PrintBol
    };

    // Subscribe to the PrintPage event of your custom PrintDocument.
    printDocument.PrintPage += new PrintPageEventHandler(printDefault.Question);

    // Start the printing process.
    printDocument.Print();

    this.PrintComplete = true;
}

}

And my class .... I figured that my class is an extension of PrintDocument, but I'm not sure. One of the dumb requirements is that I need the MongoDb collection document to generate the BOL form to print, because that has all my data I need to populate the document I'm trying to create. I'm not really sure if my design is sound or not, and may have to think of an alternative. But I feel like I'm really close, just missing something that I didn't think of.

namespace SimpleBol.Classes.DirectPrint
{
public class PrintDefault : PrintDocument
{
public BILLOFLADINGS Bol { get; set; } = null!;

    // Create a PrintPage event handler method
    public void PrintDocument\_PrintPage(object sender, PrintPageEventArgs e)
    {
        // Create the fonts we need to print with
        Font fontTitleBold = new Font("Arial", 16, FontStyle.Bold);
        Font fontTitleRegular = new Font("Arial", 16, FontStyle.Regular);
        Font fontLargeBold = new Font("Arial", 12, FontStyle.Bold);

I can't help you with the print class, but I do have an idea about the testing. Do you have MS Office installed on your development machine? If so, I believe that also installs a "Print to PDF" printer driver. You could use that to print to a PDF file instead of the printer.

The difficult we do right away... ...the impossible takes slightly longer.

I didn't think of that! I have CutePDF that I print all my orders with, before I email them. Thanks!

On top of that, ChatGPT should not be used to write code. It sucks at writing anything beyond "Hello World" and WILL lead you down incorrect paths.
